I communicate directly with both of them, have met both in person and had lengthy discussions with each.  I believe they love Bitcoin for the same three four reasons I do:

1. The technology behind bitcoin is interesting and novel; Satoshi solved a long-standing problem in computer science.
2. The adoption of Bitcoin would change the world for the better, by giving us a better form of money.
3. The potential to earn of a huge amount of money.
4. I'm a wannabe felon.

Roger Ver has done a huge amount to further Bitcoin adoption.  Perhaps more than anyone else besides Satoshi Nakamoto.  He truly loves Bitcoin and wants to see all of the world adopt it.  That people now abuse him for trying to fix the problem of high fees and unreliable confirmations is heart-breaking for me.
